I bought this thinking I can use the smartphone (Sony Xperia Z3) as a handheld recorder. The audio volume of the recording is silent nowhere near did of a 'professional' recorder. My Xperia Z3 phone Recognizes IT as a stereo microphone and has an app for adjusting audio input settings (you can see attached images). I've tried it on a Samsung Galaxy S3 and the recording is mono, Must Be Galaxy's port fault. So works on at iPad4.
